Common SmartLCT errors & problems
What techs run into most, and what's usually behind it. The step-by-step fix for your exact software is in Ask Roadie.
- Step-by-step fixGet the fix →
Cannot import a cabinet configuration file made in NovaLCT
Likely cause: Older SmartLCT builds predate the .rcfgx import feature; the interchange was added in V3.5.3 for NovaLCT V4.6.0+ files.
- Step-by-step fixGet the fix →
Image cut off, scaled, or wrong size on the wall
Likely cause: The sending card maps a fixed input canvas to the wall; a resolution mismatch between GPU output and sending card causes cropping/scaling.
- Step-by-step fixGet the fix →
MCTRL4K not recognized as a sending device in SmartLCT
Likely cause: Support for MCTRL4K was added with a 64-bit Windows requirement; a 32-bit OS or older build will not list it.
- Step-by-step fixGet the fix →
Need to build a curved, rotated, or irregular (freeform) screen
Likely cause: Rotation and freeform mapping depend on receiving-card/controller capability; without an A-series card or MCTRL R5 the rotation options are unavailable.
- Step-by-step fixGet the fix →
Screen black, partially lit, or garbled after configuration
Likely cause: The receiving card drives the LED modules by an exact pixel map; any dimension/scan mismatch produces black, partial, or scrambled output.
- Step-by-step fixGet the fix →
SmartLCT cannot detect connected sending/receiving cards; controller shows offline
Likely cause: SmartLCT talks to the controller over a single serial/USB session; a missing driver, unpowered device, or a port already claimed by NovaLCT blocks detection.
- Step-by-step fixGet the fix →
Standard first-time screen configuration workflow in SmartLCT
Likely cause: SmartLCT configures the signal chain in order (input -> sending card -> receiving card -> screen layout); following the tab order sets each stage correctly.
- Step-by-step fixGet the fix →
Visible dark or bright seams/lines between cabinets or batches
Likely cause: Adjacent cabinets and different batches have slight brightness/chroma offsets; seam and batch adjustment normalize the boundary and per-cabinet output.
- Step-by-step fixGet the fix →
Which controllers does SmartLCT support, and when should we migrate off it
Likely cause: NovaStar froze SmartLCT and moved new-hardware support to NovaLCT and VMP; new controllers will not appear in SmartLCT.
- Step-by-step fixGet the fix →
Which SmartLCT version to install and does it run on Mac
Likely cause: SmartLCT is the only NovaStar sync-config tool with a macOS build; version choice matters for controller and .rcfgx support.
